The Inaccessible_Boot_Device error is another BSOD (stop code) issue that can arise due to various causes. This particular error has a 0x0000007b stop code and often arises during the system startup.
As the Inaccessible_Boot_Device error occurs in such a moment, it’s more serious than random BSOD errors because it stops PCs from booting correctly. Consequently, some users can’t log in to and utilize their computers when this error arises.
The same Inaccessible_Boot_Device error appears on Windows 10 too. There are, however, a few ways you can feasibly fix it. To do so, you’ll need to make the most of Windows 11’s built-in system tools, which often provide the best solutions for BSOD issues.
Is this a blue, green, or black screen error?
In Windows 10, the Inaccessible_Boot_Device error is a Blue Screen of Death error. However, Microsoft has changed the background color of BSOD errors to black in Windows 11. Therefore, this issue is a Black Screen of Death one in the latest desktop platform, but it’s still the same error.
To make things a bit more confusing, Windows 11 Insider Preview builds have Green Screens of Death errors instead of black ones. They’re the same errors with a different background color. Thus, the Inaccessible_Boot_Device error screen can also have a green background for some users.
Therefore, the Inaccessible_Boot_Device is a blue, green, and black screen error. It’s still the same issue on Windows 11 and 10 irrespective of its background color.
How can I enter Windows 11’s Advanced Recovery Options?
If you can’t get into Windows 11 because of the Inaccessible_Boot_Device error, you’ll need to enter Advanced Recovery Options during the system startup. Advanced Recovery Options is a centralized blue menu outside of Windows that includes numerous system tools and options.
Some users may be able to enter Advanced Recovery Options with the F11 keyboard key. Try pressing it shortly after turning on your PC. Then the blue Choose an option menu might open, but that’s not a universal method.
If that doesn’t work, restart the computer by pressing and holding its Power button for about 5 to 10 seconds when you see the Windows logo during the startup. Force the shutdown in that way three times. After you restart your PC like that three times in a row, an Automatic Repair screen will appear.
This screen includes an Advanced options button. Click that button to enter the Advanced Recovery Options menu. From there, you can access system tools that can feasibly fix the Inaccessible_Boot_Device error or activate Safe Mode.
You can get back into Windows with the Safe Mode option. To do so, select Troubleshoot and Advanced options. From there, select Start-up Settings and Restart. When Windows restarts, press F4 (or F5) to choose Enable Safe Mode on the Start-up Settings menu.
Thereafter, you will be able to apply the potential fixes below as outlined in Safe Mode. That mode is a special diagnostic one for Windows 11, which loads with only minimal driver sets and services.

Can I apply the potential fixes above without entering Safe Mode?
The Advanced options menu outside of Windows includes System Restore, Command Prompt, Startup Repair, and Uninstall Updates tools. So yes, you can apply most of the resolutions above by opening the required tools for them from there.
To reset the platform outside of Windows, you’ll need to select Troubleshoot and Reset this PC within Advanced Recovery Options. Then the Reset this PC utility open. Thereafter, you can select the options to reset Windows 11 as required.
The Advanced options menu also includes a System Image Recovery utility. If your PC has a system image backup, that option could resolve the Inaccessible_Boot_Device error.
If those potential resolutions aren’t enough to fix the Inaccessible_Boot_Device error on your computer, the issue might be due to faulty hardware. In which case, you might need to remove and replace faulty internal hardware modules to solve it.
It’s not recommended for home users to remove faulty internal components themselves. So, consider returning your PC to its manufacturer for repairs if the above resolutions don’t resolve the error. If your computer is still within its warranty period, its manufacturer might fix the issue free of charge.
However, give the potential resolutions above a try first before turning to any IT support or repair services. Although they’re not entirely guaranteed fixes, there’s a good chance at least one of them will resolve the Inaccessible_Boot_Device error on your PC.
